GAS-BURNER.

Specification of Letters Patent.

Patented June 12, 1906.

Application filed January 30, 1906. Serial No. 298,647.

whichit appertains to make and use the same.

My invention relates to gas-burners; and it consists of certain parts and arrangement of parts such as will be hereinafter fully explained and then particularly pointed out in tion,- Fig. 2, a similar view showing V sition of the parts with the the claims which .conclude this application.

The object of my invention is to automatically prevent the escape of gas from the burner after the gas-cock has been opened until certain mechanical appliances have been operated and, furthermore, to automatically cut off the gas-supply whenever the pressure goes down and afterward is again put on.

In the accompanying drawings, which form a part of this application, Figure l is a vertical sectional elevation illustrating my improvement with the parts in normal posithe position of the parts when the'gas-pressure is put on, and Fig. 3 a similar view showing the popressure on and immediately after the mechanical appliances have beenoperated to allow the escape of gas through the tip.

Similar numbers of reference denote like parts in the several figures of the drawings.

1 is the base-section of the'burner, interior-1y threaded at the bottom for attachment to a gas-fixture and having a reduced tubular projection 2 at the top, which projection is open at both ends, so as to provide an inlet or passage 3.

4 is a sleeve secured to said section and surrounding the projection 2. 5 isan airspace between the inner wall of this sleeve and the outside of the tubular projection 2.

6 is a cap-shaped diaphragm which rests by gravity upon the top of the projection 2 so as to practically close the passage 3, the sides of the diaphragm extendingdownloosely within said space, so that there will be ample provision made for the escape of gas between the projection 2 and sleeve 4 and the sidesof the diaphragm. The top of the diaphragm is concave, and resting loosely on thecentral portionof this diaphragm is a ball-valve 7.

8 is the upper section of the burner, which is secured to the top of the sleeve4 and. is provided with a horizontally-disposed partition 9, which divides this upper section into two compartments.

' 10 is a nipple which is screwed within this partition, soas to be adjustable, and is pierced, so as to provide a vertically-disposed gasduct 11- immediately above the valve 7 and in line with the passage 3. The bottom of this nipple depends so as to provide a valveseat for the ball-valve,and thereby forms an annular recess 12 between the nipple and the sides of the section 8.

13 is the burner-tip, secured in the usual manner in the upper .end of the section 8.

14 is a small tube screwed within the side of the section 8; 15, a small plunger-pin extending through this tube within thesection 8 16 a coil-spring thistubeand around the pin, and 17 a small head secured to the outer end of the pin. This pin is horizontally disposed, ,and its normal position is in a direct line with the ball-valve 7 when the latter is in its elevated position against the seat at the bottom of the nip le 10, so that it will be readily understood t at when the pin is thrust inwardly it will strike the ball if the latter is in this elevated position.

The lower or basesection 1 and the sleeve 4 may of course be integral but it is cheaper and more convenient for assembly to make them separate. They both nevertheless constitute what I shall hereinafter term the lower section of the burner.

The operation of my improvement is as follows: When the gas is turned on, the diaphragm will be elevated, thus bringing the ball-valve against the bottom of the nipple, so that when the gas shall have escaped be tween the tubular projection, the sides of the base-section, and the sides of the diaphragm itcannot pass through the duct 11. By driving the plunger-pin 1,5 inwardly it will strike the ball and thrust the latter away from the duct 11 into the recess 12, thus permitting the pressure of the as to still further elevate the diaphragm unti the latter comes in contact with the ball, as shown at Fig. 3, whereupon a.clear ,passagesway is open for the gas, so that .the latter may pass through the tip 13.

It frequently happens, particularly when the supply of gas depends upon a coin-controlled apparatus, that the pressure goes down andafterward is .put on, and-this has of coursecaused a great many fatalities and has frequently filled a whole building with the escaping gas. Also a gas-cock on a fixture has often been accidentally opened, or else when not provided with a suitable stop 'has been turned too far around, thereby causing the same results as those above noted. Such results are impossible when my improved gasburner is used, since should the pressure go down when the gas is turned on the diaphragm will drop and close the passage 3 while the ball-valve will roll down and automatically assume its normal position upon the diaphragm, and when the pressure is again put on the diaphragm will be elevated, and thus cause the ball-valve to seat a ainst the bottom of the nipple and prevent t e escape of gas up through the tip.

While I prefer that the nipple should be adjustable through the partition 9, so that my improvement may respond to a greater or lesser pressure, nevertheless this nipple may be a fixture forming a part of the partition, if desired. It is not absolutely necessary to utilize the plunger-pin to displace the ball, since a light tap against the side of the burner will cause this displacement and allow the pressure of the gas to elevate the diaphragm to the position shown at Fig. 3.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device of the character described, the combination of the lower section having a tubular passa e, a diaphragm which by gravity normally 0 oses the upper end of said passage, a valve supported by said diaphragm and capable of displacement, the upper section secured to the lower section and having a gas-duct immediately above said valve whereby the upward movement of the diaphragm will cause the valve to close said duct, and means for displacing said valve thereby opening the duct and establishing a free passage-way for the gas.

2. In a device of the character described, the combination of the lower section having a tubular passa e, a diaphragm which by ravity normally 0 oses the upper end of saifpassage, a valve supported by said diaphragm and capable of displacement, the upper section secured to the lower section and having a horizontal partition through which extends a duct and whose lower central portion forms a depending valve-seat surrounding said duct and immediately above said valve, and means for thrusting said valve from its seated position.

3. In a device of the character described, the combination of the two sections one having a tubular passage while the other has a horizontal partition provided with a duct immediately above the upper end of said passage, a gravity-diaphragm which normally closes said end, a valve supported by said diaphragm whereby the gas-pressure will ele vate the diaphragm and cause the valve to close said duct, and means for thrusting the valve away from the duct into a position between the diaphragm and the partition whereby said diaphragm will be prevented from closing the duct and a free passage-way for the gas will thereby be afforded.

4. A gas-burner comprising complementary sections containing lower and upper gaspassages separated from each other by an intervening space, a diaphragm which normally closes the lower passage, a mechanically-displaceable valve supported by said diaphragm immediately below the upper passage whereby when the diaphra m is elevated by asressure said passa e wi 1 be closed by saidva ve, and means for t usting said valve away from said passage and into a position where it will prevent the. diaphragm from closing said upper passage.

5. gas-burner comprising complementary sections containing lower and upper gaspassages separated from each other by an intervening space, a diaphragm which normally closes the lower passage and has a concave upper surface, a ball-valve which normally rests freely upon the center of said surface immediately below the upper passage, a partition which horizontally divides the upper section and through which the upper gas-passage is pierced said partition being recessed near said passage, and means for forcing, said ball into the recessed portion of said artition.

6. n a device of the character described, the combination of the lower section havin a tube extending upwardly therethrough and an air-space around said tube the latter being open at top and bottom and constituting the inlet-passage for the gas, a cap-shaped gravity-diaphra m which normally rests upon the top of sai tube and whose sides extend loosely within said air-space, a valve supported by said diaphragm and capable of displacement, the upper section secured to the lower section and having a gas-duct immediately above said valve whereby the upward movement of the diaphragm will cause the valve to close said duct, and means for displacing said valve thereby opening the duct and establishing a free passage-way for the 23 7.
